Abstract

PROBLEM TO BE SOLVED: To make the colors of a photographic image and a pattern image well balanced by changing the color of the printed pattern image in accordance with the color of the photographic image on the periphery of a position where the pattern image is printed. SOLUTION: In the case of printing a void photographic image like the pattern image such as a void character, the photographic image made void like the pattern image is printed by inputting an image signal for making the area of photographic sensitive material 2 where void is made like the pattern image on a liquid crystal board 31 in a dark color in the liquid crystal board 31, and absorbing the specified rate of exposing light. In the case the sub-exposure of the pattern image such as a black character is performed later and the periphery of the position where the sub-exposure of the pattern image is performed is thick, the image signal for making an area corresponding to the periphery of the position of the material 2 where the pattern image is printed on the liquid crystal board 31 in the dark color is inputted in the liquid crystal board 31, and the specified rate of the exposing light is absorbed, so that density is made low.

In the prior art, the amount of color exposure control of a pattern image to be printed is adjusted so that the pattern image has a desired color or the pattern image has a desired color. Is described, but it is not described how to determine a desired color. Therefore, although these techniques exist as ideas, it is actually difficult to determine the color of a pattern image that matches a photographic image. And
A printing machine that prints a color photographic image from a photographic original on a photographic photosensitive material by a projection printing method and prints a pattern image at a position overlapping with the color photographic image separately from printing of the color photographic image has recently been produced. In most cases, the color of the pattern image is black or the color balance of the exposure control amount of the pattern image is fixed.

An object of the first invention is to print a color photographic image from a photographic original on a photographic photosensitive material by a projection printing method and print a pattern image at a position overlapping with the color photographic image separately from the printing of the color photographic image. In a printing machine, the operator can more easily or omit the thinking of selecting the color of the pattern image, and the pattern becomes a color of the pattern image in which the balance between the color of the photographic image and the color of the pattern image becomes good. This is to enable image printing.

Further, in the prior art, it is necessary to control a pattern image to have a desired density and to control a color exposure control amount of a pattern image to be printed so that the pattern image has a constant density. Is described. However, if the pattern image is made to have a desired density or the color exposure control amount of the pattern image to be printed is controlled so that the pattern image has a constant density, a poor-looking image may be obtained. I found it to be. The cause of this problem is as follows. When the exposure amount of the photographic image around the pattern image is low, if the exposure amount of the pattern image is significantly higher than the exposure amount of the photographic image around the pattern image, first, the density of the pattern image The difference in density between the photographic image around the pattern image and the image around the pattern image increases, and an image with a strong sense of discomfort can be obtained.Secondly, the stray light of the exposure of the pattern image affects the photographic image around the pattern image, It has been found that an abnormal image in which the density changes as the photographic image is closer to the pattern image is obtained.

A second object of the present invention is to increase the difference between the density of the pattern image and the density of the photographic image around the pattern image to produce an image with a strong sense of incongruity, or to make the photographic image around the pattern image closer to the pattern image. An object of the present invention is to make it possible to prevent a pattern image from being distinguished from a photographic image without causing an abnormal image whose density changes.

Further, in the prior art, it is described that a photographic image around a position of a pattern image has a density formed at a low exposure amount. It does not describe how to determine whether to do so. Therefore, although these techniques exist as ideas, it is actually difficult to determine the color of a pattern image that matches a photographic image. Therefore, a printing machine which prints a color photographic image from a photographic original on a photographic photosensitive material by a projection printing method and prints a pattern image at a position overlapping with the color photographic image separately from printing of the color photographic image has been finally produced in recent years. However, there is nothing to lower the exposure amount of the photographic image around the position of the pattern image.

A third object of the present invention is to print a color photographic image from a photographic original on a photographic photosensitive material by a projection printing method and print a pattern image at a position overlapping with the color photographic image separately from the printing of the color photographic image. In the printing machine, the operator's thinking for selecting how low the density of the photographic image around the position of the pattern image can be simplified or omitted, and the density of the photographic image around the position of the pattern image can be reduced. Is to balance the unnaturalness of the image with the difficulty of seeing the pattern image so that the image can be printed to obtain a better image.

Further, as described in Japanese Patent Application Laid-Open No. 61-238039, a liquid crystal or a polarizing element is provided in close contact with a photographic original, and the amount of exposure around a pattern image to be printed is determined according to the position of the pattern image to be printed. In general, the frame image of a photo manuscript is quite small, so unless a liquid crystal or a polarizing element has a very small pixel unit, the exposure amount of an appropriate area cannot be lowered, In addition, the jaggedness of the liquid crystal or the polarizing element in pixel units becomes conspicuous. Further, as described in Japanese Patent Application Laid-Open No. 7-225433, if a mask for white printing or a mask for a cut filter is inserted to lower the exposure amount in the vicinity of printing a pattern image, the exposure at a certain location may be reduced. It is only possible to reduce the amount, and cannot cope with the case where the position of the pattern image is changed.

A fourth object of the present invention is to print a color photographic image from a photographic original on a photographic photosensitive material by a projection printing method and print a pattern image at a position overlapping with the color photographic image separately from the printing of the color photographic image. In a printing machine, even if a pixel unit of an image-like transmittance changing member such as a liquid crystal or a polarizing element is not used, the jaggedness of a pixel unit of an image-like transmittance changing member such as a liquid crystal or a polarizing element is conspicuous. Instead, it is an object of the present invention to reduce the exposure amount of a photographic image at an appropriate position around a pattern image with respect to various pattern image positions.

A fifth object of the present invention is to print a color photographic image from a photographic original on a photographic photosensitive material by a projection printing method and print a pattern image at a position overlapping with the color photographic image separately from the printing of the color photographic image. By using a printing machine, it is possible to lower the exposure amount of a photographic image at an appropriate position around a pattern image for various pattern image positions without using a liquid crystal or a polarizing element. is there.

Further, in the prior art, it is described that the exposure amount of the photographic image around the position of the pattern image is reduced to increase the exposure amount of the pattern image. It does not describe a method for lowering the exposure amount of the pattern image as compared with the exposure amount of the image.

A sixth object of the present invention is to provide a printing machine for printing a photographic image from a photographic original on a photographic photosensitive material by a projection printing method, wherein the exposure of the pattern image is compared with the exposure amount of the photographic image around the position of the pattern image. That is to be able to lower the amount.

Further, when a pattern image is printed by projection printing from a lith film on which a pattern image is recorded as described in JP-A-61-238039,
It is necessary to stop the photographic photosensitive material separately from the stage for printing the photographic image and print the pattern image, which complicates the control and the efficiency of the printing is not good.

Further, as described in JP-A-7-225433, a pattern image is printed by a printing head which individually guides light from a light emitting element which emits light according to an image signal of the pattern image to a photographic photosensitive material by an optical fiber. In such a case, the photographic photosensitive material must be conveyed at a constant speed, which requires a high degree of conveyance control, and the apparatus itself becomes expensive.

A seventh object of the present invention is to stop the photographic material separately from the stage for printing the photographic image, to eliminate the need to print the pattern image, to transport the photographic material at a constant speed, and to reduce the cost. To print the pattern image.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, specific examples of the present invention will be described as embodiments, but the present invention is not limited thereto. Further, in the embodiments, although there are definite expressions for terms and the like, they show preferred examples of the present invention, and do not limit the meaning or technical scope of the terms of the present invention.

Embodiment 1 FIG. 1 shows a schematic configuration diagram of a printing machine according to this embodiment. This printing machine simply prints a photographic image recorded on a photographic original, multiplexes a pattern image such as a character image with a photographic image recorded on the photographic original, and prints a photographic image recorded on the photographic original. And printing a photographic image by providing a low-exposure portion (white portion in negative color photographic paper) like a pattern image.
Hereinafter, a detailed description will be given based on FIG. 1 and appropriately referring to other drawings.

In this printing machine, the photographic original 1 and the photographic photosensitive material 2 are not limited. However, in order to obtain a print for appreciation, when the photographic original 1 is a color negative film, the photographic photosensitive material 2 is a color negative photographic paper. When the photographic original 1 is a color positive film, the photographic photosensitive material 2 is preferably a color reversal photographic paper, and when the photographic original 1 is a monochrome film, the photographic photosensitive material 2 is preferably a monochrome photographic paper. Hereinafter, the description of the density and the like will be made on the assumption that the photographic original 1 is a color negative film and the photographic photosensitive material 2 is a color negative photographic paper having γ of 2 to 3. It is a color positive film, and the photographic light-sensitive material 2 can be applied to a case where it is a color reversal photographic paper.

First, the structure of the printing machine will be described.

The exposure light source section 5 has the following structure. The light source lamp 51 emits light when exposing a photographic document and capturing an image. Then, the infrared transmitting mirror 52 reflects the light emitted on the rear side of the light source lamp 51 toward the diffusion box 57. The heat-insulating filter 53 transmits only visible light from the light source lamp 51 and allows infrared rays to pass downstream of the heat-insulating filter 53 to the exposure light path, so that the photographic document 1 and the like do not particularly have heat. Yellow cut filter 54,
Magenta cut filter 55, cyan cut filter 5
Reference numeral 6 is appropriately inserted into the exposure light path for exposure by the white color reduction method according to the exposure control amount of each primary color. The diffusion box 57 is for making the exposure light uniform exposure light with no positional variation. Specifically, a plurality of scattering acrylic resin plates are provided vertically to the exposure optical path, and It has a structure in which four sides between the plate and the last acrylic resin plate for scattering are surrounded by mirrors.

The negative carrier 6 is located immediately downstream of the diffusion box 57 on the exposure light path side. The negative carrier 6 conveys the photo document 1 so that the frame image of the photo document 1 is positioned on the negative mask 61 and is imaged or printed. The negative mask 61 is opened to a predetermined size corresponding to the size of the frame image of the photographic document 1, so that unnecessary stray light is not transmitted downstream of the exposure optical path.

A printing lens 7 is provided on the downstream side of the exposure optical path of the negative carrier 6. The printing lens 7 is used to convert a photographic image recorded on the photographic document 1 positioned on the negative mask 61 of the negative carrier 6. Is formed on the photographic material 2 placed on the photographic material transport table 4. The mirror 8 is composed of a negative carrier 6 and a printing lens 7.
Are provided so as to be insertable / removable in an exposure optical path between them. When capturing a photographic image recorded on the photographic document 1 positioned on the negative mask 61 of the negative carrier 6, the mirror 8 is inserted into the exposure optical path, and the photographic document 1 positioned on the negative mask 61 of the negative carrier 6 is captured. When the light from the photographic image recorded in the photographic image is reflected on the imaging device 12 and printed from the photographic image recorded on the photographic original 1 positioned on the negative mask 61 of the negative carrier 6, the mirror 8 is separated from the exposure optical path. So that it does not interfere with baking.

The image pickup device 12 forms an image of a photographic image recorded on the photographic document 1 positioned on the negative mask 61 of the negative carrier 6 by forming it on the image pickup device by the image pickup lens 11. Then, image information of the photographic image recorded on the photographic original 1 is obtained. Then, a control unit (not shown) determines a printing condition based on the obtained image information and performs various controls of operations described later.

A liquid crystal member 3, which is an imagewise transmittance changing member, is provided on the downstream side of the exposure optical path of the printing lens 7 and on the upstream side of the exposure optical path from the photographic photosensitive material conveying table 4. Liquid crystal member 3
As shown in FIG. 2 which is a perspective view showing the relationship between the liquid crystal member 3 and the photosensitive material transport table 4, and FIG. 3 and FIG. It is slightly above the photographic light-sensitive material 2 placed on the carrier 4 and
Occasionally, as shown in FIG. 4, the liquid crystal plate 31 moves to a position where the liquid crystal plate 31 comes into close contact with the photographic material 2 placed on the photographic material transport table 4. In any case, the liquid crystal plate 3 of the liquid crystal member 3
Numeral 1 is parallel to the photographic material at the printing position. Further, the liquid crystal plate 31 has a size capable of covering the photographic photosensitive material of the maximum size that can be printed by the main printing machine and covering the entire exposure optical path to the photographic photosensitive material of the maximum size that can be printed by the main printing machine. Liquid crystal plate 3 around liquid crystal plate 31
1 is provided. The surface of the liquid crystal plate holding frame 32 on the downstream side of the exposure light path is flush with the surface of the liquid crystal plate 31 on the downstream side of the exposure light path, and the inner surface 321 of the liquid crystal plate holding frame 32 is formed by the reflected light of the liquid crystal plate holding frame 32. It is inclined to the upstream side of the exposure light path so as not to enter the plate 31. In the liquid crystal plate 31, the ratio between the transmittance when transparent and the transmittance when darkened is 10 times or more.

The photographic light-sensitive material conveying table 4
Is transported while sucking the air by depressurizing the air, and the flatness of the printing position is high. Then, the photographic photosensitive material 2 is suctioned by air decompression at the time of printing, so that the photographic photosensitive material 2 is brought into close contact and has a flatness. The photographic light-sensitive material 2 is surely conveyed without leaving the photographic light-sensitive material conveyance stand 4. Then, the photographic material transporting table 4 transports the photographic material 2 in the left direction in FIG. Then, the photographic photosensitive material 2 on which the photographic image recorded on the photographic original 1 has been printed is conveyed to the exit of the printing machine (not shown) through the sub-exposure section 9.

The sub-exposure section 9 prints a pattern image such as a character on the photographic material 2 by using strobe light. Hereinafter, the sub-exposure unit 9 will be described. Strobe light source 91
Are provided inside the dark box 92. The dark box 92 is configured such that light does not enter from other directions and does not leak to other directions except for the surface on the photographic material transport table 4 side. Then, the liquid crystal plate 9
3 are provided. A liquid crystal plate holding frame 94 that supports the liquid crystal plate 93 is provided around the liquid crystal plate 93. The liquid crystal plate holding frame 94 is fixed to the dark box 92. The strobe light source 91 is a point light source, and a velvet 95 is provided on the inner surfaces of the liquid crystal plate holding frame 94 and the dark box 92 as a light preventing member for preventing light reflection. By functioning as a point-like light source, blurring of a pattern image such as a character is prevented. In addition, a filter 96 is provided between the strobe light source 91 and the liquid crystal plate 93 and very close to the strobe light source 91.
The filter 96 covers the entire exposure path from the strobe light source 91 to the liquid crystal plate 93, and corrects the color balance of the strobe light source 91 so as to perform neutral exposure on the photographic material 2. The filter 96 is provided very close to the strobe light source 91 between the strobe light source 91 and the liquid crystal panel 93, so that even if flare is generated by the filter 96, its influence is minimized.

Next, the printing operation will be described with reference to FIG.

First, in S1, the photographic light-sensitive material transport table 4 is
The photographic photosensitive material 2 that has already been printed is discharged, the next photographic photosensitive material 2 is conveyed, positioned at the printing position, and the process proceeds to S2. At the time of this discharge, when passing through the sub-exposure section 9,
As will be described later, sub-exposure using strobe light is performed in some cases.

In S2, it is determined whether or not a white photographic image such as a pattern image such as a white character is to be printed on the photographic material 2. When printing a white photographic image such as a pattern image such as white characters on the photographic material 2,
If the process proceeds to S6, and if a white photographic image such as a pattern image such as a white character is not to be printed on the photographic material 2, the process proceeds to S3.

In S3, a pattern image such as a black character is subjected to sub-exposure later, and it is determined whether or not the periphery (that is, the background) of the position where the pattern image is sub-exposed later is dark. If a pattern image such as a black character is subjected to sub-exposure later, and the area around the position where the pattern image is sub-exposed later (that is, the background) is dark, S5
Then, the pattern image such as black characters is subjected to sub-exposure later, such as when the pattern image such as black characters is not sub-exposed later or when the area around the position where the pattern image is sub-exposed later (that is, the background) is thin. Unless the area around the position where the pattern image is to be sub-exposed later (that is, the background) is dark, the process proceeds to S4.

In step S4, normal printing is performed, and printing of the photographic image on the photographic material 2 is completed. When performing normal printing, all the pixels of the liquid crystal plate 31 are in a transparent state. FIG. 6 shows a photograph original 1 by the normal printing as described above.
FIG. 4 is a diagram showing a print obtained when a frame image recorded in the photographic photosensitive material 2 is directly printed on a photographic photosensitive material 2.

In step S5, a pattern image such as a black character is sub-exposed later, and printing is performed to reduce the density of the background when the periphery (ie, background) of the position where the pattern image is sub-exposed later is dark. That is, when the pattern image is printed separately, when the exposure amount for printing the photographic image is high around the position where the pattern image is printed, the exposure amount around the position where the pattern image is printed is lowered and printed. Then, the printing of the photographic image on the photographic material 2 is completed.

This is because, for example, when the background of the position 14 where a pattern image such as a character is printed is dark as shown in FIG. 6, there is a problem that the pattern image such as a character is difficult to see. An image signal for darkening a region 33 corresponding to the periphery of the position where the pattern image is printed, inside the main exposure path 34 of the edge of the photographic photosensitive material 2 on the liquid crystal plate 31 is input to the liquid crystal plate 31. Area 33 is darkened (transmittance is lowered) to absorb a predetermined ratio of the exposure light. Then, as shown in FIG. 8, the density 24 around the position where the pattern image is printed is reduced. In this manner, when a pattern image such as a character is sub-exposed as described later, the pattern image 2
5 is clearly separated from the background.

When a pattern image such as a black character is subjected to sub-exposure later, printing is performed to reduce the density of the background when the area surrounding the position where the pattern image is printed (that is, the background) is dark, or normal printing is performed. Is determined based on the original exposure amount (Eb) of the photographic image around the position of the pattern image to be printed.
c, Egc, Erc). This exposure amount (Ebc, Egc, Erc) is equivalent to density information D obtained by imaging the color photographic image recorded on the photographic original.
It is calculated from bfc, Dgfc, Drfc and the color exposure control amounts Eb, Eg, Er when printing the color photographic image. Then, the exposure amounts (Ebc, Egc, E
If all of rc) are equal to or greater than the predetermined exposure amounts (EbC, EgC, ErC), printing is performed to reduce the density of the background when the area around the position where the pattern image is printed (that is, the background) is dark.

In step S6, the liquid crystal member 3 is moved so as to bring the liquid crystal member 3 into close contact with the photographic material 2 as shown in FIG. Proceed to S7.

In step S7, a white photographic image such as a pattern image such as white characters is printed, and the flow advances to step S8. Hereinafter, a method of printing a white photographic image such as a pattern image such as white characters will be described.

This is useful, for example, when the background of the position 14 where a pattern image such as a character or the like is white as shown in FIG. 6 is dark, as shown in FIG. An image signal is input to the liquid crystal plate 31 for darkening a region 37 for performing pattern pattern-like whitening inside the region 36 corresponding to the edge of the photosensitive material 2, and the region 37 of the liquid crystal plate 31 is darkened and exposed. Absorbs a predetermined percentage of light. Then, as shown in FIG. 11, a photographic image in which a pattern image is outlined is printed. In this manner, by bringing the liquid crystal plate 31 into close contact with the photographic material 2, the white outline of a pattern image such as a character can be clearly recognized without blur.

In S8, as shown in FIG. 3, the liquid crystal member 3 is moved so as to separate the liquid crystal member 3 from the photographic material 2, and printing of a photographic image on the photographic material 2 is completed.

After finishing this flow, a flow for printing the next photographic light-sensitive material 2 is started.
If the flow for printing the next photosensitive material 2 is not started, only the photosensitive material 2 is discharged.

Next, the sub-exposure will be described. The sub-exposure section 9 is parallel to the photographic light-sensitive material transport table 4 and
Can be moved in a direction perpendicular to the transport direction of. And
While the photographic image is being printed on the photographic light-sensitive material 2, it moves to a position corresponding to the position where the pattern image is printed. When the photographic light-sensitive material 2 is conveyed and passes through a position where a pattern image is printed, strobe light is emitted to perform sub-exposure. Since the emission of the strobe light of this embodiment is 20 μsec, even if the strobe light is conveyed at a conveying speed of 250 mm / sec, which is the faster conveying speed of the printing machine, the blur amount is 5.0 × 10 ⁻³ mm or less. There is no problem at all.

At this time, the liquid crystal plate 93 receives an image signal corresponding to the pattern image to be printed, and makes only an area corresponding to the pattern image to be printed transparent, and the other areas are darkened. Then, a pattern image 25 as shown in FIG. 9 or a pattern image 26 as shown in FIG. 13 is printed.

At this time, the exposure amount is not constant. Hereinafter, the exposure amount when printing a pattern image will be described with reference to FIG. If the exposure amount of the image around the position for printing a pattern image (background) is as large of an exposure amount E ₂ it is, can not be completely identified unchanged almost concentration if not greater exposure of the pattern image, the exposure amount E Exposure is performed with a sufficiently large exposure amount E _S according to ₂ . Then, the exposure amount of this portion is the exposure amount E ₂ for printing a photographic image.
And the exposure amount E _S of the pattern image becomes E ₂ + E _S , and the print density D _{2S at} the position where the pattern image is printed is:
Occurs Concentration D ₂ and the density difference [Delta] D _2S print when no baking a pattern image, it is possible to identify the pattern image. That is, it can be clearly identified as shown in FIG. In the case where the print density becomes close to the maximum density without changing the exposure amount of the photographic image around the position where the pattern image is printed, only the exposure amount of the photographic image around the position where the pattern image is printed is reduced.

On the other hand, when the exposure amount of the photographic image around the position where the pattern image is to be printed (background) is as small as the exposure amount E ₁ , the exposure amount of the pattern image is
_When it is large as _S , firstly, the stray light of the exposure of the pattern image becomes a sub-exposure effect, and the density of the photographic image becomes higher as the pattern image becomes closer to the image.
Since the density difference as _1S may become a harsh image is too large, exposed with a sufficiently small exposure amount E _L in accordance with an exposure amount E _1. Then, the sum E ₁ + E _L next to the exposure amount E _L of the exposure amount E ₁ and the pattern image for the exposure of this portion to burn photographic image, density D _1L position of prints baked pattern image, the pattern image When the image is not printed, a density difference ΔD _{1L from} the density D ₁ of the print is generated, and the pattern image can be identified. Not an image. That is, a clear image as shown in FIG. 13 is obtained.

In this way, when a large number of prints obtained from photographic light-sensitive materials by printing different photographic images by the present printing machine, for example, 100, are compared, a print pattern image is printed regardless of operation input. By observing or measuring the density, it can be identified that the exposure amount of the pattern image to be printed is changed in accordance with the exposure amount of the photographic image around the position.

In the above description, the printing of the pattern image is a neutral exposure for the photographic photosensitive material. However, when the photographic original is a color photographic original and the photographic photosensitive material is a color photographic photosensitive material, By printing the filter 96 with a yellow cut filter, a magenta cut filter, and a cyan cut filter that can be inserted into and removed from the exposure light path, the printing of the pattern image may be printing of a non-neutral color balance. In this case, the color density D estimated in a print in which a color photographic image around the position where the pattern image is to be printed is obtained.
bc, Dgc, and Drc are converted to density information Dbf obtained by imaging the color photographic image recorded on the photographic original.
It is estimated from c, Dgfc, Drfc and the color exposure control amounts Eb, Eg, Er for printing the color photographic image by the following equation.

(Dbc, Dgc, Drc) = F (Eb−
Dbfc, Eg-Dgfc, Er-Drfc) Here, F (B, G, R) is the density DB, DG, of the print obtained from the exposure B, G, R given to the photographic material.
This is a function showing a characteristic curve giving DR.

Then, the obtained concentrations (Dbc, Dgc,
From Drc), the densities (Dbp, Dgp, Drp) that are estimated to have a good color balance are determined. However, the following expression is satisfied.

Dbp ≧ Dbc Dgp ≧ Dgc Drp ≧ Drc Then, the exposure amount (Ebp, Egp, Erp) necessary to give the density (Dbp, Dgp, Drp) is estimated by the following equation.

(Ebp, Egp, Erp) = F ⁻¹ (Db
p, Dgp, Drp)-(Eb-Dbfc, Eg-Dg
fc, Er−Drfc) where F ⁻¹ (DB, DG, DR) is the inverse function of F (B, G, R).

Then, for example, a filter 96 and a strobe light source 91 are printed so that the pattern image is printed on the photographic material at the exposure amount (Ebp, Egp, Erp) at which the pattern image was obtained.
The sub-exposure unit 9 is controlled, for example, by controlling the amount of emitted light.

In this way, when a large number of prints obtained from photographic light-sensitive materials by printing different color photographic images by the printing machine are compared, for example, 100 sheets, the pattern images of the prints can be changed regardless of the operation input. It can be observed that the color of the pattern image to be printed has changed according to the color of the color photographic image around the printing position.

When performing printing to reduce the exposure amount, filters 382 and 384 for covering apart from the photographic material 2 are inserted to an appropriate position. The filters 382 and 384 for covering the photo-sensitive material 2 in close contact therewith are formed of a member having almost no transmittance in order to completely remove the white color.
